After writing and illustrating Henrietta, World War II Hen, Anthea Brigham returned to write, and also illustrate, another children's book, Roger the Rooster Leaps to the Rescue. It is the tale of a clever rooster who puts new-found skills into play to protect his hens. Removed from his chicken coop and sent to a petting zoo, Roger practices his jumping ability every day while attempting to escape the zoo. After a fox kills one of the hens in Roger's home coop, he is brought back to defend his brood. The fox returns for another kill, but Roger, now a champion leaper, bounces high and lands upon the back of the interloper, driving him off. The hens are saved, the farmer is relieved to have a steady supply of eggs, and Roger is the hero of the hencoop!
